Abstract

In this work atmospheric plasma spraying of SiC and Si3N4 was investigated. Plasma spraying of these ceramics raises several problems since they would tend to decompose instead of melting at elevated temperatures during the process. To circumvent this problem the non-oxide ceramics were deposited as a composite powder mixed with non-oxide ceramic particles resulting in a ceramic/ceramic composite structure. Our findings were that using such a composite feedstock powder both oxidation and decomposition of the non-oxide particles could be avoided. A vitrified phase was also developed in the coating.
